I haven’t updated to Sierra yet, and unfortunately I cannot reproduce your issue, as my old wrapper works for me. Here are a couple more to try out, based on Wineskin 2.6.2 with Wine version 1.5.0 (which is known to also solve the white noise issue) and CX14.0.0. They should of course work for the offline game, Deep Island and TOC TPotS.

It’s a bit more complicate, because first you will need to install Uru: Complete Chronicles. It’s a Windows-only game, so you will need a wrapper; I might be a bit biased, but I suggest using mine .

You will need to know how to open the wrapper, i.e. right-click on it and select Show Package Content.

I wrote a step-by-step guide to use the wrapper to install the game (it’s easier than it looks!). Let me know if there’s anything unclear. Have a look at the whole thread, if you have time.

Once you have Uru: CC ready, the procedure is the same as for Windows: download the patcher, unpack it, then copy the files in the Uru: CC folder, then point the wrapper to Uru.exe (there should be no need to set a compatibility mode with the wrapper).

I had to UNTICK all the screen tick options (decorate windows etc) and with some Wineskin games/shards I had to try various screen options until I found one that worked.

Anyway, I can now access ALL the shards and also a couple of old legacy Windoze programs and other games which were also hanging.I didn't need to change any engines or wrappers ....just screen options.

I guess they did something with the graphic configurations/setting/metal in High Sierra.
